Heated Basement Sunova

I have a 2016 Sightseer 33C. My rig has a heater vent in my wet bay that blows hot air when the propane furnace is blowing.

If you have a question call Winnebago in Forest City, Iowa, talk to a service technician and they can tell you exactly how your RV is configured.

Safe travels. JD

It will be fine. Really the same coach as my Winnebago Vista. I did have a pump freeze-up when the temp dropped to 0 in Tonopah NV a couple years ago. The utility bay (which has passages throughout the 'underbelly') has two 'holes' that connect to an area behind and under the main bed. Just general convection wasn't moving enough warm air down through the holes so I added a small computer fan that runs anytime the main coach power switch is on. Cured that issue!

Thanks for this idea. I have one of those plugins and it would keep things warm, but prevent overheating. I also can use a remote thermometer to monitor the temp. Good idea. I cannot find any furnace venting in this bay.

They make a thermostatically controlled plug that you can use with an incandescent trouble light. This will turn the light on at around 32 degrees and protect your wet compartment.
Some coaches have a vent that will direct SOME heat in to the basement from the furnace, but not all coaches have this feature.

Question is: do you have enough propane to keep the tanks warm at 15*?
